| Abstract | ||
| Two trails were carried out to study the relationship between sexual characteristics of buck and doe with some blood parameters in New Zealand white rabbits . Atotal of 10 male rabbits ( 6-7- months old) and 8 primiparous doe rabbits (6 months of age)have been used in the first and second traits, respectively .The results of the first trail showed that buck trails were within the normal range .The correlation coefficient values, were positive (P> 0.01) between ejaculate volume and total protein , albumin and between blood electrolytes (Ca , Na and K) and each of sperm motility and sperm concentration were negative(P> 0.01 or 0.05 ) between Ca , Na and K and each of dead and abnormal spermatozoa . Inorganic phosphorus was positively correlated. (P> 0.05) with sperm concentration. The correlation coefficient values between globulin, urea-N or creatinine and each of libido, semen physical characteristics and fertility ability, were not significant . In the second trial , the mean values of doe trails were found within the normal range . the correlation coefficients were significantly ( P> 0.01)positive between total protein and conception rate and between creatinine and each of litter weight at day 21,litter gin weight at weaning also between Ca and each of gestation length , gain weight at weaning , Na and litter size at day 21 and between K and gestation length .Correlation coefficient values between globulin, urea-N or P and each of doe traits , were not significant . Generally, the overall means of blood constituents were nearly or within the normal level of Rabbits . | ||
